If the service exited with an error condition, the service specific
code that is logged in the event log is visible here.

CheckPoint

If the service is shutting down, holds the current check point number.
This is used by the SCM as a kind of heart-beat to detect a wedged service
process. The value of the check point is best interpreted in
conjunction with the WaitHint value.

WaitHint

If the service is shutting down it will set WaitHint to a checkpoint
value that will indicate 100% completion. This can be used to
implement a progress indicator.
